JS Solar vs Vikram Solar - solar panel manufacturer comparison

JS Solar, formally Yixing JS Solar Co., Ltd, is a Chinese cell and module manufacturer headquartered in Wuxi, Jiangsu province, active in the solar sector since 2004 and operating its own production base since 2007. The company states a production capacity of around 20 GW, though actual annual module shipments are reported in the low single-digit GW range, placing it among mid-tier Chinese suppliers rather than the largest global brands, and clear, independent confirmation of current Tier 1 status was not found. Vikram Solar, based in Kolkata, India, was founded in 2006 and re-entered BloombergNEF's Tier 1 module manufacturer list in 2024, with nameplate module capacity that has grown to roughly 9.5 GW following new plants such as Vallam and Gangaikondan. On institutional footprint and verifiable bankability, Vikram Solar currently holds the stronger position.

JS Solar's catalog spans monocrystalline modules from roughly 200 W to 670 W, with a modest share of bifacial panels, positioning it as a flexible option for residential rooftop and smaller commercial installations. Vikram Solar has been shifting its newer capacity toward N-type TOPCon technology, with Hypersol TOPCon modules rated at 615-640 W and efficiencies up to about 23.7 percent, alongside its first HJT module launches, reflecting a stronger push into utility-scale ground-mount and higher-yield commercial and industrial (C&I) projects.

For an international buyer choosing between the two, Vikram Solar's confirmed Tier 1 bankability and larger, TOPCon-oriented manufacturing base make it the more defensible default for utility-scale or bank-financed projects, while JS Solar can be a reasonable choice for smaller residential or commercial jobs where formal Tier 1 documentation and long-term institutional track record matter less; the two brands are not strictly interchangeable given this bankability gap.
